The article deals with bladder cancer staging. A general discussion about staging is found in cancer staging.
General
- TNM staging the most commonly used.
- Urachal carcinoma has its own staging system - see Sheldon staging system.[1]
TNM staging system
Tumour
| T stage | Criteria |
|---|---|
| Ta | non-invasive papillary carcinoma |
| Tis | carcinoma in situ |
| T1 | lamina propria invasion |
| T2 | muscularis propria invasion |
| T3a | microscopic extravesicular invasion |
| T3b | macroscopic extravesicular invasion |
| T4a | extension into the uterus, vagina or prostate |
| T4b | extension into the abdominal wall or pelvic wall |
Notes:
- The most important distinction is between T1 and T2. This is dealt with in the muscularis propria invasion in the urinary bladder article.
- T2 is typically managed with a radical cystectomy or radical cystoprostatectomy.
- Upstaging based on cystectomy/cytoprostatectomy pathology common - range 20-80%.[2]
- Not all fat is perivesicular. Fat within the bladder wall (submucosa) is well-described.[3][4]
Nodes
| N stage | Criteria |
|---|---|
| N1 | one regional lymph node metastasis |
| N2 | more than one regional lymph node metastasis |
| N3 | metastasis to the common iliac lymph nodes |
